Document Type and Number:
Japanese Patent JP3152491
Kind Code:
B2
Abstract:
PURPOSE: To provide the title process which can be applied when a composite material is produced by combining it with another polymer and can be performed in an organic solvent under gentle conditions.
CONSTITUTION: An aromatic/heterocyclic block copolymer is obtained by preparing two oligomers separately by reacting an aromatic diaminodithiol compound in which the hydrogen atom of each thiol is substituted by an (un)substituted alkyl group or an aromatic diamine compound with a dicarboxylic acid derivative in an organic solvent, reacting these two oligomers in an organic solvent to prepare a precursor copolymer, and heating the precursor copolymer to close the thiazole rings.
